Apical transportation associated with ProTaper® Universal F1, F2 and F3 instruments in curved canals prepared by undergraduate students
OBJECTIVE This study evaluated apical transportation associated with ProTaper Universal Fl, F2 and F3 rotary files in curved canais prepared by undergraduate students. MATERIAL AND METHODS Twenty mesial roots of mandibular molars with curvatures ranging between 25° and 35° were selected. Mesiobuccal canals were instrumented by twenty students with the ProTaper system (Dentsply-Maillefer, Ball...
متن کاملComparison of canal transportation in simulated curved canals prepared with ProTaper Universal and ProTaper Gold systems.
OBJECTIVES The purpose of this study was to assess the ability of ProTaper Gold (PTG, Dentsply Maillefer) in maintaining the original profile of root canal anatomy. For that, ProTaper Universal (PTU, Dentsply Maillefer) was used as reference techniques for comparison. MATERIALS AND METHODS Twenty simulated curved canals manufactured in clear resin blocks were randomly assigned to 2 groups (n ...
متن کاملGeometric and dimensional characteristics of simulated curved canals prepared with proTaper instruments
OBJECTIVE This study identified which regions of ProTaper instruments work during curved root canal instrumentation. MATERIAL AND METHODS Twelve ProTaper instruments of each type, S1, S2, F1, and F2, were assessed morphometrically by measuring tip angle, tip length, tip diameter, length of each pitch along the cutting blades, and instrument diameter at each millimeter from the tip. Curved can...
متن کاملRoot canal volume change and transportation by Vortex Blue, ProTaper Next, and ProTaper Universal in curved root canals
Objectives The aim of this study was to compare root canal volume change and canal transportation by Vortex Blue (VB; Dentsply Tulsa Dental Specialties), ProTaper Next (PTN; Dentsply Maillefer), and ProTaper Universal (PTU; Dentsply Maillefer) nickel-titanium rotary files in curved root canals. Materials and Methods Thirty canals with 20°-45° of curvature from extracted human molars were used...
متن کاملCentring ability and apical transportation after overinstrumentation with ProTaper Universal and ProFile Vortex instruments.
AIM To evaluate morphological changes to the major foramen after overinstrumentation with ProTaper Universal and ProFile Vortex Ni-Ti rotary instruments. METHODOLOGY Twenty-eight mesiobuccal canals of maxillary and mandibular first molars were divided into two groups of 14 canals each. The root canals were prepared with ProTaper Universal or ProFile Vortex instruments. ProTaper and Vortex in...
